Given:

The coordinate of point R in quadrilateral RUST are (2,4).

R is dilated by a scale factor of 3, centered at the origin, followed by the translation (x, y)\to (x+4,y).

To find:

The coordinates of R' after dilation and translation.

Solution:

If a figure is dilated by a scale factor of 3, centered at the origin, then

(x,y)\to (3x,3y)

We value R(2,4).

R(2,4)\to R_1(3(2),3(4))

R(2,4)\to R_1(6,12)

The rule of translation is:

(x, y)\to (x+4,y)

Using this rule, we get

R_1(6,12)\to R'(6+4,12)

R_1(6,12)\to R'(10,12)

Therefore, the coordinates of point R' are (10,12) and the correct option is B.

Calculate the mean of each data set below. Can you find any shortcuts that allow you to find the mean without having to do much calculation? Homework help  6, 10, 6, 10 11, 12, 12, 13, 12 0, 5, 4, 8, 0, 7

Answer: To find the mean of the given observations. we just need to first find the sum of the given observations and the divide the calculate sum by the total number of observations.

So here:

Sum of of observations =6+ 10+ 6+10+11+12+12+13+12+0+ 5+ 4+ 8+ 0+7=116

Number of observations = 15

Therefore, the mean =\frac{116}{15}= 7.733

Shane wants to plant 28 marigold plants and 36 rose plants in his garden. What is the greatest number of rows possible if each r
Dennis_Churaev [7]

Answer:

HCF=2*2=4

Step-by-step explanation:

Given :   Shane wants to plant 28 marigold plants and 36 rose plants in his garden  

To Find :  the greatest number of rows possible  each row has the same

number of marigold plants and the same number of rose plants.​

Solution:

marigold plants  = 28

rose plants = 36

To find  the greatest number of rows possible  if each row has the same

number of marigold plants and the same number of rose plants.​

we need to find HCF of 28 and 36

28 = 2 x 2 x 7

36 = 2 x 2 x 3 x 3

HCF = 2 x 2  = 4

greatest number of rows possible  is 4
